Such 30*5c2921b0SApple OSS Distributionsmessages were sent in response to the various 31*5c2921b0SApple OSS Distributions<strong>device_</strong>...<strong>_request</strong>... 32*5c2921b0SApple OSS Distributionscalls. It is assumed when using 33*5c2921b0SApple OSS Distributionsthose calls that some task is listening for reply messages on the port named as a 34*5c2921b0SApple OSS Distributionsreply port to those calls. The <strong>device_reply_server</strong> 35*5c2921b0SApple OSS Distributionsfunction performs all 36*5c2921b0SApple OSS Distributionsnecessary argument handling for a kernel message and calls one 37*5c2921b0SApple OSS Distributionsof the device server functions to interpret the message. 38*5c2921b0SApple OSS Distributions<h3>RETURN VALUES</h3> 39*5c2921b0SApple OSS Distributions<dl> 40*5c2921b0SApple OSS Distributions<p> 41*5c2921b0SApple OSS Distributions<dt> <strong>TRUE</strong> 42*5c2921b0SApple OSS Distributions<dd> 43*5c2921b0SApple OSS DistributionsThe message was handled and the appropriate function was called. 44*5c2921b0SApple OSS Distributions<p> 45*5c2921b0SApple OSS Distributions<dt> <strong>FALSE</strong> 46*5c2921b0SApple OSS Distributions<dd> 47*5c2921b0SApple OSS DistributionsThe message did not apply to this device handler interface and no other 48*5c2921b0SApple OSS Distributionsaction was taken. 49*5c2921b0SApple OSS Distributions</dl> 50*5c2921b0SApple OSS Distributions<h3>RELATED INFORMATION</h3> 51*5c2921b0SApple OSS Distributions<p> 52*5c2921b0SApple OSS DistributionsFunctions: 53*5c2921b0SApple OSS Distributions<a href="device_open.html"><strong>ds_device_open_reply<strong></a>, 54*5c2921b0SApple OSS Distributions<a href="device_write.html"><strong>ds_device_write_reply<strong></a>, 55*5c2921b0SApple OSS Distributions<a href="device_write_inband.html"><strong>ds_device_write_reply_inband<strong></a>, 56*5c2921b0SApple OSS Distributions<a href="device_read.html"><strong>ds_device_read_reply<strong></a>, 57*5c2921b0SApple OSS Distributions<a href="device_read_inband.html"><strong>ds_device_read_reply_inband<strong></a>, 58*5c2921b0SApple OSS Distributions<a href="device_read_overwrite.html"><strong>ds_device_read_reply_overwrite<strong></a>. 59
